APPLIANCE FOR SUPPORTING CARRIAGE-WINDOWS.

SPECIFICATION forming part of Letters Patent No. 349,647, datedSeptember 21, 1886.

' Application filed July 13, 1886. Serial No. 207,942. (No model.)

1 0 all whom it may concern.-

-Be it known that I, CHARLES GODFREY GiiMPEL, a citizen of England,residing at Leicester Square, in the county of Middlesex, England, haveinvented a new and useful Ap- -pliance for Holding Carriage-\Vindows andother Sliding Sashes at any Required Height, of which the following is aspecification.

My invention relates to means of holding carriage-windows or othersliding sashes at any required height, permitting them to be easilyraised, supporting their weight but allowing them to be lowered byapplication of slight pressure in addition to their weight. Iefi'ectthis by applying apparatus, which Iwill describe, referring tothe accompanying drawings, illustrating my invention applied to acarriage-window. Figure 1 is a vertical section of the door and windowof a carriage, showing the window raised to its full height. Fig. 2 isan enlarged side view, and Figs. 3 and 4 are plans of the plate B andbar E, respectively.

In the recess under the window, into which the sash is usually lowered,I place a bar, A, securing it at its lower end, as illustrated inFig. 1. To the under side of the sash-frame I fix a plate, B, from whichproject downward two studs. 0 and D. that pass through holes in across-bar, E. The bar A passes through a hole in the bar E, and alsothrough a hole in the plate B. Around the stud G is a helical spring,tending to press the one end of the bar E down, and around D is'also aspring, tending to press the other end of E up, the tendency of thosesprings being to cant the bar E into a slightly-inclined position.

In pulling up the sash by means of a handle, F, at its top, the clutchoffers little or no resistance, but when the sash is let go its weight,acting through the spring on G, depresses one end of E, while the springon D keeps up the other end. The bar E, being thus somewhat canted, ismade to grip the bar A with sufficient frictional hold to prevent thesash from descending; On applying the hand to push down the sash thisresistance continues until a collar, d, on the stud D, meeting the barE, causes that end of the bar to shift a little downward, thus releasingthe grip. The sash may be fully raised and made to catch over thesillbar G, as shown in Fig. 1. For releasing it when it is in thatcondition it is only necessary to press the top part of the sashoutward, causing the sash to cant a little over a cross-bar or two sidestuds, H, as a fulcrum,

Having thus described the nature of my invention and the best means Iknow for carrying the same into practical effect, I claim As anappliance for holding carriage-win dows and other sliding sashes, thecombination, with a vertical bar fixed in the recess below the sash, ofa horizontal bar embracing the vertical bar and carried by the bottom ofthe sash, said horizontal bar being acted upon by two springs tending tocant it, so as to clutch the vertical bar, while a stud or collar on thesash makes the horizontal bar release,

its hold when the sash is depressed, substantially as herein described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witncsses, this second day of July, A. D.1886.
